Abstract

L'invention porte sur un procédé de détection d'objets mobiles, y compris des personnes. Une surveillance, une sûreté et une sécurité améliorées sont assurées par utilisation d'une caméra monoculaire et d'une source de lumière structurée, par calcul de trajectoire, calcul de vitesse, ou comptage de personnes et autres objets passant à travers un plan laser disposé perpendiculairement au sol, et qui peuvent être établis n'importe où près d'un portail, d'un couloir ou d'une autre zone ouverte. Une sécurité améliorée est assurée pour des portails, tels que des portes pivotantes, des sas de sécurité, des portes battantes, des portes coulissantes, etc., à l'aide de la caméra monoculaire et de la source de lumière structurée pour détecter et, facultativement, empêcher des violations d'accès, telles que l'« accès à califourchon » et le « passage en double »
